Here we have the Sifam VU meter 0-6mA Fe/Nfe, made in England. On the face is Radio Systems, 21090/2 in black & 21091/2 in red and it measures about 3 3/4 inch wide by 2 7/8 inch high. This working meter was removed from a radio station mixing console and is in good condition, several available, thanks for looking.
